Package: libsane Version: 1.0.27-3.2 Severity: normal I use xsane, started from GIMP with a Canon LiDE 220.
It works fine at resolutions up to 1200 dpi. When I choose 2400 dpi or 4800 dpi, the following happens: xsane hangs for a while. Sometimes, after a short or long wait (trying to scan an area of 1 cm by 2 cm at 4800 dpi, there was a hang of 20 min before the messagea appeared) , I get an error message "Konnte Scanner nicht starten: Ungültiges Argument" (German for: could not start scanner, invalid argument) or "Konnte Scanner nicht starten: Fehler während Geräte I/O" (German for: could not start scanner, error during device I/O). Afterwards further scans at low resolutions also give the error message. After retsarting xsane, I can scan at resolutions up to 1200 dpi again. According to the manufacturer of the scanne, Canon, the LiDE supports up to 4800 dpi. However, there is a footnote "When scanning in high resolution, the scan size is restricted." in their device description, and Windows users indeed report that he Scanner won't let them scan large areas at full resolution. If this is really a hardware restriction that cannot be worked around it seems sane should: 1) Allow scans of small areas at 2400 and 4800 dpi 2) Immediately give an informative error message when attempting to scan large areas at 2400 or 4800 dpi. -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.2.0-2-amd64 (SMP w/4 CPU cores) Kernel taint flags: TAINT_WARN Locale: LANG=de_DE.utf8, LC_CTYPE=de_DE.utf8 (charmap=UTF-8), LANGUAGE=de_DE.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libsane depends on: ii acl 2.2.53-5 ii adduser 3.118 ii libavahi-client3 0.7-4+b1 ii libavahi-common3 0.7-4+b1 ii libc6 2.29-2 ii libgphoto2-6 2.5.22-3 ii libgphoto2-port12 2.5.22-3 ii libieee1284-3 0.2.11-13 ii libjpeg62-turbo 1:1.5.2-2+b1 ii libsane-common 1.0.27-3.2 ii libsnmp30 5.7.3+dfsg-5 ii libssl1.1 1.1.1c-1 ii libtiff5 4.0.10+git191003-1 ii libusb-1.0-0 2:1.0.23-1 ii udev 242-7 Versions of packages libsane recommends: pn sane-utils <none> Versions of packages libsane suggests: ii avahi-daemon 0.7-4+b1 pn hplip <none> -- no debconf information
